Title: Controlling apparatus of activated sludge process
Inventor: MASUDA MASAHIRO
IPC: C02F3/12
Filed: 1983-09-19
Abstract: PURPOSE:To keep desired quality of treated water stable over a long period of time, by providing a converter for converting the output of a redox electrometer to a nitration rate and a deviation detecting circuit for imparting the deviation value of the output of said converter and a preset value to a control part. CONSTITUTION:When an aeration tank 1 is a perfectly mixing type, a redox electrometer (OP meter) 31 avoids the vicinity of an introducing port for inflow water or return sludge and is arranged to a uniformly mixtured place. When the tank 1 is a forcible flow type, the OP meter 31 is arranged in the vicinity of an outflow port. The output of the OP meter 31 is inputted to a nitration rate converter 32 to obtain a nitration rate in output. This nitration rate is inputted to a deviation detecting circuit 33 and the deviation output with a set nitration rate is sent out from the circuit 33. A deviation output value is inputted to a DO control part 5 and the output of the nitration rate converter 32 is inputted to a SRT control part 8 while the set values of both control parts are altered by the aforementioned deviation output value and the nitration rate.

Title: Controller for amplitude degree
Inventor: SHIBATA YOJI
IPC: G06T1/00
Filed: 1985-08-07
Abstract: PURPOSE:To attain the correction of output variance due to the difference of outputs among the photodetecting elements of a photodetecting element train as well as the variance of this element train due to the fluctuation of intensity of a light source, by calculating the amplification degree for each scan and correcting the output of each photodetecting element. CONSTITUTION:Storage circuits 60 and 140 store values VD and VF respectively when a lamp 11 is turned off. While a storage circuit 50 stores a value VB and the output 403 of an amplifying circuit 130 has a value VA when the lamp 11 is turned on. Under such conditions, a differential arithmetic circuit 70 calculates VB-VD in order to obtain the genuine standard value. While a differential arithmetic circuit 80 calculates VA-VF to obtain the genuine output value. Then an amplification factor arithmetic circuit 90 calculates G(VW-VT) to obtain the amplification degree when the output 701 of the circuit 70, the output 801 of the circuit 80 and an amplifying constant are defined as VT, VW and G respectively. Based on this calculated amplification degree, the output signal is amplified. These arithmetic processes are carried out in response to the output of each photodetecting element on a photodetecting element train 10. Then the output of each photodetecting element is corrected.

Title: Manufacture of centrifugal force molding
Inventor: WATANABE YOSHIHARU
IPC: B28B21/30
Filed: 1995-06-19
Abstract: PURPOSE: To manufacture a centrifugal molding having no surface roughening or particularly a concrete product by rotatably treating at an initial speed before centrifugal force molding. CONSTITUTION: An initial speed stage of shorter rotating time is conducted at smaller GNo. before starting a low speed as a method of starting at the low speed at the time of centrifugal force molding to prevent surface roughening. The initial speed rotating treatment is conducted before the centrifugal force molding, and the conditions suitably include 1G or less and 5sec to less than one minute. It is necessary to set the initial speed to 1G or less of very slow speed rotation in order that concrete is not laminated to the inner surface of a form at all but the concrete is rather slid in the form. Thus, the surface roughening of a product is prevented. After the initial speed is started, normal low, intermediate and high speeds are conducted. In this manner, a centrifugal force molding without surface roughening or particularly a concrete product can be manufactured.

Title: Vane type compressor
Inventor: ONO MITSUYA
IPC: F04C28/06
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To surely avoid the compression of liquid without decreasing discharge performance during starting. SOLUTION: The front side end face 1c of a cam ring 1 and a groove 40 of predetermined sectional area to communicate a valve storage room 1a and a compression room 12a with each other are provided. When the operation of a compressor is stopped, lubricant is tending to enter into a back pressure room 13a in the process that pressure in the compressor is balanced, but cooling medium gas in the valve storage room 1a (a discharge room 10) escapes through the groove 40 to the compression room 12a, pressure in the back pressure room 13a rapidly rises and pressure in the compressor is balanced in a short time, so that the quantity of the lubricant entering into the back pressure room 13a can be restricted. As a result, noise due to the compression of liquid is reduced when the operation of the compressor is restarted.

IPC: G01G3/00
Filed: 1987-07-13
Abstract: PURPOSE:To improve accuracy, variance in characteristics, and reproducibility by polishing the contact surface of a sensor mount part for a pressure sensor into a plane. CONSTITUTION:When a load is placed on a diaphragm 7 through a load transmission means 2, the diaphragm 7 flexes until two upper and lower electrodes 5 contact each other, but the diaphragm 7 is supported by the sensor mount part 20 as a rigid body even if the load is further applied thereafter and no unreasonable stress is applied to the diaphragm 7 and substrate 8. Even if, however, the mount part 20 is strained by tens of mum at this time, the substrate 8 transmits it as pressure to the displacement of the lower electrode 5. For the purpose, the surface of the mount part 20 is polished to have high-accuracy flatness, and the substrate 8 can be mounted in a stable state. Consequently, no pressure is applied from the side of the substrate 8 at the time of weight measurement, so that only the load from the body to be measured is measured extremely accurately.
